WATER-CLOSET.

Specification of Letters Patent No. 18,550, dated November 3, 1857.

To all whom it may concern:

vBe it known that I, FRANCIS MCCHAN, of V'Vashington city and Districtof Columbia, have invented a new and useful Improvement inTater-Closets; and I' do hereby declare that the following is a full,clear, and exact description of the construction and operation ofthesame, reference being had to the annexed drawing, forming part of thisspecification, in which- Figure 1 is a side view of the apparatus. Fig.2 is a section on w, taken through axis of spindle s.

Similar characters of reference in the several iigures denote the samepart.

My invention has reference to the manner of regulating the flow of waterto the pan, after it has been used.

In the drawing A is the pan and B the,

pipe conveying the water thereto, and in communication with a chamberC', as shown in Fig. 2. This chamber receives the supply of waterthrough opening a, closed by a valve b. This valve rests upon the mouthof the opening, and is there held by an india rubber diaphragm C towhich it is attached said diaphragm constituting the top chamber C. Thewall of the chamber C is perforated and connected with the main pipe Dby a small pipe CZ as shown in Fig. 2. The pipe el has a stop cock 7c bywhich the size of water passage may be regulated.

Through the roof E of chamber C runs a spindle s, secured at bottom toan elastic diaphragm f stretched across the chamber above the mouth ofpipe d.

The action of this construction is as follows Chamber C being incommunication with the supply pipe, by pipe d, will fill with waterabove valve b; and as the upper surface of the valve is greater than thearea of opening a, the valve will rest close to its seat, and no waterbe permitted to pass to pipe B. Pressure downward upon spindle s willforce water through pipe d into pipe D against the head of water. And onthe removal of this pressure, the head of water through pipe D will liftvalve Z) and water iiow to the pan A. This flow of water will continue,until suflicient water passes through pipe Z to lill the displacement inchamber C, and close valve Z). This time will depend on the size ofopening regulated by the stop cock 7c. The shaft s rises above the sideof the box and is forced down by the weight of the person occupying theseat I. A spring m lifts this shaft when the occupant of the seat rises.In practice therefore, the length of time the water is to run isregulated by the stop cock 7c. The manner of closing the valve b may.with suitable modifications, be adapted to wash stands, bath tubs, andother analogous uses.

Vhat I claim and desire to secure by Letters Patent, is-

The adjustable communication Z 7c between the supply pipe D and thechamber C above the valve b, in combination with the displacingdiaphragm f or its equivalent, arranged and operating substantiallyasset forth. 4

In testimony whereof, I have hereunto signed my name before twosubscribing witnesses.

FRANCIS MCGHAN.
